411toppm reads a .411 file, such as from a Sony Mavic
camera, and con- verts it to a PPM image as output.

Output is to Standard Output.

The originator of this program and decipherer of the
.411 format, Steve Allen <sla@alumni.caltech.edu>, has
this to say about the utility of this program: Theres so
little image in a 64x48 thumbnail (especially when you have
the full size JPG file) that the only point in doing this
was to answer the implicit challenge posed by the manual
stating that only the camera can use these files.
